Emotional appeal from children of mother murdered a decade ago

The children of a murdered Melbourne woman have made an emotional appeal for information to help catch their mother's killer.

Jesmine Crossthwaite-Petrov was just nine years old and her brother Nicholas was eight when their mother was murdered.

"She was just so loving and caring. She just loved us so much - we were everything to her," Jesmine said.

Cindy Crossthwaite lived at a Melton South home with her three children, but in June 2007 the family was ripped apart.

The alarm was raised when the 41-year-old mother failed to pick up her two eldest children from school.

Her father Philip discovered his daughter's body.

"I unlocked the door. I walked in, and found her body; deep breath," Mr Crossthwaite said.

Her youngest son, Jonas, aged just 15 months at the time, had been alone in the house with his mother's lifeless body.

"That breaks my heart. I don't know what happened, if he did see anything, or anything like that, I don't know how that's affected him," Jesmine said.

Detectives have announced a million-dollar reward to help persuade anyone with information to come forward.

"I still can't find a reason why anyone would do that," Nicholas said.

"Someone was playing with her," Jesmine added.

Since the 10-year anniversary of Cindy's murder police say they have received information which links more than one person to the killing.

They also believe the mother of three was being stalked in the weeks leading up to her death.
